Answer :
A photosynthetic reaction is the formation of the glucose and oxygen molecule by water and carbon dioxide. 12 moles of water will be used in the reaction.
What are moles?
Moles are the ratio of the mass of the substance to the molar mass of the substance.
In the photosynthetic reaction, 6 moles of carbon dioxide and 6 moles of water are utilized to produce 1 mole of a glucose molecule and 6 moles of oxygen.
From this, it can be said that the number of moles consumed of carbon dioxide and water will be equal and in the ratio of 1:1.
The number of moles of carbon dioxide will be equal to that of the water molecule and will also be equal to the ratio of the mass of carbon dioxide to the molar mass of carbon dioxide.
The moles of water will be calculated as:
[tex]\begin{aligned}\rm moles &= \rm \dfrac{\text{mass of CO}_{2}}{\text{molar mass of CO}_{2}}\\\\&= \dfrac{528}{44.01}\\\\&= 12\;\rm moles\end{aligned}[/tex]
Therefore, option A. 12 moles of water will be used.
